Ukrainian forces have advanced three to four kilometers into Russia’s Belgorod region, engaging in battles with Russian troops, according to Russian military bloggers and independent analysts.
Military expert Emil Kastehelmi of the Black Bird Group told Reuters Ukrainian troops had penetrated Russia’s first line of defense, though he noted that their ability to launch a major breakthrough remains unlikely.
Not something I’ve thought about before, but if anything, the Kursk incursion showed russia that they have to respond seriously to Ukraine crossing the border and move in a lot of troops and equipment.
This means that when Ukraine does something like this, russia is forced to respond in force, and move a lot of gear around. With the current state of russian equipment and the drone war, moving a lot of equipment is likely to result in quite a few losses, both because of wear and stuff breaking down on its own, and because concentrations of gear and troops on the move are prime targets for Ukrainian drones.
